This paper explores employee experiences of induction in the Big Four accountancy firms to understand how induction influences new recruits' career aspirations.

Using Bourdieusian sociology, this article adopts an interpretivist multi-method approach through focus groups and semi-structured interviews with 28 newly appointed accounting professionals. The study defines newly appointed as those who have experienced induction within the last two years of their employment.

The study's findings challenge the authenticity of induction from a shared employee consensus. It cites contagious spin, regarding career progression opportunities espoused during induction, at odds with the reality of work, ultimately contributing towards unfulfilled employee aspiration. As current strategies suggest that the intersection between employee aspiration and employer provision in the accountancy profession, is too broad, this study argues for more collaborative inductions. In addition, it proposes that accountancy firms should re-evaluate their current strategies and co-construct more authentic inductions that benefit all stakeholders to develop a stronger psychological contract that positively influences employee aspiration.

The paper posits action-learning as a solution to address employee aspiration in induction campaigns in the accountancy profession.

As aspiration is the genesis of motivation and engagement, this study’s findings suggest that the use of an action-learning ethos in induction activities may provide an opportunity to explore the complexities of employee socialisation and provide a voice to new recruits attempting to influence any tensions or disappointment that may arise, as unmet career aspirations emerge.

The paper posits action learning as a solution to address employee aspiration in induction campaigns in the accountancy profession.

Although the importance of teacher induction is widely acknowledged, how teachers experience inductions, particularly those conducted in under-resourced areas, remains underexplored.

This study narrates a novice teacher's induction experience in a Chinese high school, from the perspectives of professional capital and community, social realist theory, practice architecture and teacher agency. The participant, Ming, reflected on a broad array of formal and informal induction activities and participated during the induction period.

Through the three-dimensional narrative space, namely broadening, burrowing and storying and re-storying, five themes emerged from Ming's induction experience: (1) heightened awareness of the meaning of teaching, (2) interacting with various professional communities, (3) professional identity tension and development, (4) the discursive influence of various aspects of culture and (5) the influence on future professional development. Overall, this narrative study shows that teacher expertise and identity development play central roles in teacher induction, and context acts as an important mediating factor in teacher induction. These findings echo the importance of teachers' agency in inductions. The implications for facilitating novice teacher induction are also discussed.

This study contributes to a nuanced understanding of a novice teacher's induction experience in China from the perspectives of practice architectures, professional capital and professional community. The conclusion highlights the importance of professional capital and agency during Ming's induction period. This paper unpacks the complexity of teacher induction by revealing new ways of thinking about induction.

Teachers in the initial stages of their career need support. The quality of their development will depend strongly on the kind of support that is given to them during induction. In this chapter, the author explains how the induction years need to be seen as a distinctive part of the teacher education continuum, building on initial teacher education (ITE) and feeding into continuing professional development (CPD). The University of Malta's Faculty of Education proposed national strategy for induction of newly qualified teachers (NQTs) stresses the need for an effective design of induction programs in terms of the type of activities, the involvement of teacher education institutions and the role of the mentor – all of which can vary, depending on the learning needs of the NQT involved. Such programs will ensure that the support provided creates opportunities to relate back to initial teacher education and to prepare teachers for career-long continuing professional development. The aim of this discussion is to evaluate the current state of professional opportunities available for beginning teachers in Malta, and to discuss an effective approach which facilitates experienced teachers to build their capacities to play a key role, through mentoring, in their new colleagues' professional learning journey.

Induction heating processes need to adapt to complex geometries or variable processes that require a high degree of flexibility in the induction heating setup. This is usually done using complex inductors or adaptable resonant tanks, which leads to costly and constrained implementations. This paper aims to propose a multi-level, versatile power supply able to adapt the output to the required induction heating process.

This paper proposes a versatile multilevel topology able to generate versatile output waveforms. The methodology followed includes simulation of the proposed architecture, design of the power electronics, control and magnetic elements and laboratory tests after building a 10-level prototype.

The proposed converter has been designed and tested using an experimental prototype. The designed generator is able to operate at 1 kVpp and 100 A at 250 kHz, proving the feasibility of the proposed approach.

The proposed converter enables versatile waveform generation, enabling advanced tests and processes on induction heating system. The proposed system allows for multifrequency generation using a single inductor and converter, or advanced tests for inductive and capacitive components used on induction heating systems. Unlike previous multifrequency proposals, the proposed generator enables a significantly improved versatility in terms of operational frequency and amplitude in a single converter.

This paper aims to investigate the efficacy of teeth flux sensors in detecting, locating and assessing the severity of short-circuit faults in the stator windings of induction machines.

The experimental study involves inducing short-circuit winding turn variations on the induction machine’s stator and continuously measuring the RMS values across teeth flux sensors. Two crucial steps are taken for machine diagnosis: measurements under load operating conditions for fault detection and measurements under no-load conditions to determine fault location and severity.

The experimental results demonstrate that the proposed approach using teeth flux sensors is reliable and effective in detecting, locating and evaluating the severity of stator winding faults.

While this study focuses on short-circuit faults, future research could explore other fault types and alternative sensor configurations to enhance the comprehensiveness of fault diagnosis.

The methodology outlined in this paper holds the potential to significantly reduce maintenance time and costs for induction machines, leading to substantial savings for companies.

This research contributes to the field by presenting an innovative approach that uses teeth flux sensors for a comprehensive fault diagnosis in induction machines. The originality lies in the effectiveness of this approach in providing reliable fault detection, location and severity evaluation.

The purpose of this paper is to describe a thriving partnership between Frostburg State University and the Garrett County Public Schools that aims to improve teacher effectiveness and retention through the implementation of a robust induction program. The initiative includes sustained, strategic mentoring; extensive professional development; and validated, competency-based microcredentials aligned to high-leverage practices.

The study included surveys and structured interviews with teaching fellows and their instructional coaches.

Having ample support and mentoring can make a significant difference for novice teachers. Partnerships between universities and local school districts can provide this critical support.

A limitation that cannot be ignored is the small number of participants in this program, all of whom are teaching in a rural school system. However, researchers working with larger school districts would add valuable knowledge to the field of study.

This paper includes implications for designing new induction programs or improving existing ones.

Mentoring, a major component of high-quality induction programs, has the potential of providing important benefits to beginning teachers including increased motivation, self-confidence, growth in professional identity, and reduced stress and anxiety.

As school systems are struggling to retain qualified teachers, high-quality induction programs are necessary.

The purpose of this study is to provide the enhancement of power quality of a high power-rated voltage source inverter driven induction motor with a three-phase, three-level neutral point clamped converter placed at the front end, while a passive power filter is connected in shunt with it. The improvement in power quality can be achieved by reducing the total harmonic distortion in source current. The controllers were designed for the linearization of the high-power induction motor drive. A control method is presented for the regulation of the common DC-link voltage.

The induction motor is modeled using its dynamic equations, and a decoupling controller is designed to linearize the nonlinear dynamics of the drive through feedback. The common DC-link voltage of the proposed front-end connected converter is monitored and controlled through a control method which feeds the pulse width modulated inverter that drives the induction motor. A passive power filter is designed to meet the reactive power requirement of the system in addition to improve the power quality.

Simulations were carried out for the proposed topology of the drive mechanism, and the outcomes were analyzed by a comparative analysis of the drive system both in the presence of the passive filter as well as in the absence of the filter. The total harmonic distortion is found to be reduced enough to meet the standards with the designed filter, and the reactive power is also compensated considerably. The input power factor at the supply side is maintained almost to unity, and the DC-link voltage of the proposed circuit topology is maintained at the desired level. The overall performance of the drive system was found to be useful and economical.

A new topology of a front-end connected three-level neutral point clamped converter to a high power-rated induction motor drive is proposed. The drive is fed by a pulse width modulated inverter with a common DC-link with the front end connected converter. A passive filter is designed with respect to the reactive power requirement of the system and connected in shunt to the converter at the supply side. Control schemes are designed and used for the drive system and also for the regulation of the common DC-link voltage of the proposed front end connected converter.

This paper aims to propose a novel simple and efficient structure for line-start axial-flux permanent magnet (LSAFPM) synchronous motor, especially regarding the permanent magnets (PMs) demagnetization reduction.

At first, a primitive raw scheme of the new structure for the LSAFPM motor is introduced. Considering this raw scheme, the levels of irreversible demagnetization in various regions throughout the entire volume of each PM are evaluated using 3 dimensional (3D) finite elements analysis (3D FEA) in full loading condition during startup until reaching steady state. Based on the results of these analyses, the primitive structural scheme is then modified through segmenting (cutting into four pieces) each PM from where the worst irreversible demagnetization levels occurred.

As will be demonstrated by the results of 3D FEA, the proposed modified structure is not only capable of successful startup and synchronization of the motor but also it considerably reduces the PM demagnetization level. Thus, the performance of the motor is significantly improved.

The demagnetization of PMs is an important effect in PM synchronous motors, which can greatly affect motor performance. Therefore, it is necessary to be considered in the motor design processes. This effect becomes much more significant in the line-start PM motors because the usual high-magnitude startup induction current produces a strong armature-reaction magnetic field, which may cause the PMs to be irreversibly demagnetized. The approach proposed in this paper provides a structural solution to mitigate the PM demagnetization effect and thereby improve the performance of an LSAFPM motor through modifying the structure of the LSAFPM motor according to an FEA-based PM demagnetization analysis. As a considerable contribution, in this analysis, the variation of demagnetization level between different areas inside each PM is computed and is considered as a basis for proposing an appropriate structural modification to mitigate the PM demagnetization effect as much as possible.

The purpose of this paper is to develop a load detection method for domestic induction cooktops. The solution aims to minimize its impact in the converter power transmission while enabling the estimation of the equivalent electrical parameters of the load. This method is suitable for a multi-output resonant inverter topology with shared power devices.

The considered multi-output converter presents power devices that are shared between several loads. Thus, applying load detection methods in the literature requires a halt in the power transfer to ensuring safe operation. The proposed method uses a complementary short-voltage pulse to excite the induction heating (IH) coil without stopping the power transfer to the remaining IH loads. With the current through the coil and the analytical equations, the equivalent inductance and resistance of the load is estimated. The precision of the method has been evaluated by simulation, and experimental results are provided.

The measurement of the current through the induction coil as a response to a short-time single-pulse voltage variation provides enough information to estimate the load equivalent parameters, allowing to differentiate between no-load, non-suitable IH load and suitable IH load situations.

The proposed method provides a solution for load detection without requiring additional circuitry. It aims for low power transmission to the load and ensures zero-voltage switching and reduced peak current even in no-load cases. Moreover, the proposed solution is extensible to less complex converters, as the half bridge.

Bearings play a critical role in the reliable operation of induction machines, and their failure can lead to significant operational challenges and downtime. Detecting and diagnosing these defects is imperative to ensure the longevity of induction machines and preventing costly downtime. The purpose of this paper is to develop a novel approach for diagnosis of bearing faults in induction machine.

To identify the different fault states of the bearing with accurately and efficiently in this paper, the original bearing vibration signal is first decomposed into several intrinsic mode functions (IMFs) using variational mode decomposition (VMD). The IMFs that contain more noise information are selected using the Pearson correlation coefficient. Subsequently, discrete wavelet transform (DWT) is used to filter the noisy IMFs. Second, the composite multiscale weighted permutation entropy (CMWPE) of each component is calculated to form the features vector. Finally, the features vector is reduced using the locality-sensitive discriminant analysis algorithm, to be fed into the support vector machine model for training and classification.

The obtained results showed the ability of the VMD_DWT algorithm to reduce the noise of raw vibration signals. It also demonstrated that the proposed method can effectively extract different fault features from vibration signals.

This study suggested a new VMD_DWT method to reduce the noise of the bearing vibration signal. The proposed approach for bearing fault diagnosis of induction machine based on VMD-DWT and CMWPE is highly effective. Its effectiveness has been verified using experimental data.
